Self-similarity matrix of Shivers from Ed Sheeran (timbre)


The song Shivers from Ed Sheeran is one of the songs in my personal playlist. This song falls under the Pop genre. Most pop songs contain an intro, verses, pre-chorus and chorus. With a self-similarity matrix, we can determine which sections of a song more or less have the same timbre, or same overall sound, and which sections are different. When looking closely at the plot, we can see two diagonal lines off the main diagonal. This means that a section of the song has been repeated. In pop songs, this is usually an indication of a repetition of the chorus.

Sprinters vs Long-distance swimmers

Introduction

Let me introduce myself. My name is Tessa, and I am a professional athlete. I swim in the national team and have won several national and international medals.

During competitions I listen to music that inspires and motivates me. So, for me and a lot of my team mates, music plays an important role in the optimal race preperation.

In swimming there are different diciplines. More specificly there are sprinters, and long-distance swimmers. Sprinters exert maximum effort for a short period of time, often no longer than 30 seconds. A long-distance swimmer does not have to be so explosive, and the exertion of their race usually lasts more than two minutes.

Of course not all swimmers lissten to music during their preperantion, but in my experience there are both sprinters and long-distance swimmers who have special playlists for competitions.

Research question

Since sprinters and long distance differ so much from each other in terms of performances, the research question I will try to answer in this portfolio is:

What are the differences between the motivation playlists of sprinters and long-distance swimmers?

First we look at the track level Spotify features of both playlists. Are there for example differences in energy, or tempo? I expect that the sprinter playlist contains more songs with higher energy and tempo.

Playlists

For this portfolio, I used several playlists of my teammates. I have subdivided these playlists in two groups, namely a playlist with tracks that sprinters listen to and one that long-distance swimmers listen to.

Typical tracks for sprinters:

  • lakdjal
  • lajdjla

Typical tracks for long-distance swimmers:

  • asda
  • ;kjakdf
